feat(example): add per-entity LLM evaluations for 985 WoN entities (S3.3)

Batch evaluation of all 988 entities via OpenRouter. 984 succeeded on
first pass; 3 failed (network errors). eval-summary --update-metrics
written with per_entity_mean=3.9556.

+- name: definition_precision
+  value: 4.0
+  max_value: 5.0
+  rationale: The definition clearly articulates the core principle of voluntary exchange
+    without government interference, specifying the limited role of government in
+    contract enforcement and fraud prevention. It avoids circularity and distinguishes
+    this concept from related but distinct ideas like laissez-faire or free markets

+- name: source_grounding
+  value: 5.0
+  max_value: 5.0
+  rationale: This entity is directly grounded in Smith's actual arguments from Book
+    IV, Chapter 8, where he explicitly contrasts the "natural system of perfect liberty
+    and justice" with mercantile restrictions. The definition accurately reflects

+- name: domain_placement
+  value: 5.0
+  max_value: 5.0
+  rationale: The "Exchange" domain is perfectly appropriate for this concept, as natural

+- name: vsm_relevance
+  value: 3.0
+  max_value: 5.0
+  rationale: This entity has moderate VSM relevance as it relates to S4 (intelligence/environmental

+    S5 (identity/policy) regarding fundamental organizing principles. However, it's
+    somewhat abstract and doesn't map cleanly to operational VSM functions.
